Definition

Anserine tendinobursitis syndrome is a pain to the inner part of the leg, just below the knee joint. It is at a location where three tendons meet and connect to bone. The muscles include the sartorius, gracilis, and semitendinosus. There are also one or more bursae at this location. A bursa is a fluid-filled sac that decreases friction between bones and muscles.

When bursae become inflamed it is called
bursitis
. When tendons become inflamed it is called
tendonitis
. For this pain syndrome, the exact cause is unknown, but it may involve injury or inflammation to the tendons or bursae.

Diagnosis

Your doctor will ask about your symptoms and medical history. A physical exam will be done. You will be asked to show exactly where you feel the pain. Often diagnosis is made by physical exam alone. Sometimes an
x-ray
is performed to rule out other injuries.

Treatment

Talk with your doctor about the best plan for you. Treatment options include the following:

Rest

You will be instructed to rest the affected knee until the pain goes away. You may also be advised to ice your knee 3-4 times a day to decrease the inflammation.

Medications

Nonsteroidal antiinflammatory drugs (NSAIDs) help with pain and inflammation. Your doctor will advise you which NSAID to take and how often.

You may also receive a steroid injection directly into your knee to relieve pain and inflammation.
